I got a 480Z! Yey!
The Video RAM was screwy, that's been replaced, working fine, then PSU has gone pop negligible voltages on all 3 outputs and slight hiss/buzz from inside the PSU. Normally it's 5V/12V/-12V...
I really have no experience with sorting out a PSU and no idea how they really work. The circuit diagram is on pg 101 of this document https://vt100.net/rm/docs/pn13821b.pdf
Is anyone able to give me some pointers in the right direction please?
